BEDSTEAD Filed Nov. 10. 1925 2 Sheets-Sheet 2 Patented Qct. 22, 1929 irre STATES PATENT orrlcr FRANK KUSTERLE, OF KENOSHA, WISCONSIN, ASSIGNOR TO SIMMONS COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE IBEDSTEAD Application led November 10, 1925. Serial No. 68,112,

My invention relates to bedsteads and more particularly to the corner construction of a three-piece bedstead. The object of my invention is to provide an improved corner construction in which the parts may be rapidly and economically manufactured of sheet metal and which may be assembled with the use of only simple tools. Other objects and advantages will appear when reference is had to the following specification when considered in connection with the accompanying drawings wherein I have illustrated a selected embodiment of my invention and wherein-' Fig. 1 is a side elevation of a bedstead einploying my improved construction.

Fig. 2 is an enlarged elevation of the corner construction.

Fig. 3 is an elevation of the side rail and post before being connected.

Fig. 4 is a section on the line `4--4 of F1g. 2.

Fig. 5 is a section on the line 5-5 of Fig. 2 and Fig. 6 is a perspective view of the various parts involved in my improved corner construction showing the parts disassembled.

Referring now to the drawings, 10 and 11 are end frames of a bedstead and 12 indicates the bed bottom which is supported by means of the end frames 10 and 11. The bed bottom comprises a side rail 13, risers 14, 14 and bed fabric 15 which includes tension springs 16, 16. The bed fabric 15 is stretched between cross members 17, 17 supported on the upward ends of the risers 14, 14.

The corner posts of the end frames 10 and 11 are provided with hook-like members 13, 18 which are adapted to engage a stud 19 secured to the respectivo risers 14. The hook-like member may conveniently be formed of a piece of angle iron having one leg thereof shaped to lit the bed post, as indicated at 20, and secured to the bed post by means of bolts 21 passing through one leg of the member and through the post and threaded into an inner strap 22.

Referring now to the construct-ion of the corner portion of the bed bottom it will be seen by an inspection of Figs. 2, 3 and 6, that the structure is maintained in position by the tension produced by the springs of the bed fabric 15. The riser 14 is a substantially Ufshaped member as may be best seen in Fig. 5, Ywherein upwardly extending arms 23 and 24 are joined atv their lower ends by means of an integral strap 25 which is bent to lit the bottoni surface of the side rail 13. One side of the U-sha-ped member is provided with a closure by means of flanges 26 and 27 which are turned inwardly from their respective sides to meet each other, as indicated at 28. The said flanges 26 and 27 are cut away attheir lower ends as indicated at 29 and 30, to permit the passage of the side rails 13 into a position wherein its lower surface at the end thereof, as indicated at 31, will engage the inner surface of the lower portion 25 of the U-shaped riser 14.

The upper end of the riser is reduced in its width and provided with an extending lug indicated at 32 which is adapted to project through slots 33 in the cross member 17 and the horizontal leg of said cross member 17 is adapted to be supported by the top edge of the inturned flanges 26 and 27 of the riser, as indicated at 34. The upwardly extending arms23 and 24 of the riser are secured together in spaced relation by means of a rivet 35 having an enlarged central port-ion to provide shoulders 36-36, and by means of the stud 19, as clearly indicated in Fig. 4.

It will be understood that the tension of the bed fabric 15 pulling on the upper end of the risers 14 tends to pull the upper ends of the risers inwardly, the risers pivoting on a. fulcrum provided at the lower edge of the inturned flanges 2G and 27, indicated at 37, resting on the upper surface of the side rails 13, but which pivoting is prevented by engagement of the strap 25 with the under surface 31 of the side rail 13.

To prevent inward sliding of the risers 14, I provide a key 38 having an enlarged'head part 39 and aftongue or tail part 40 which latter part is adapted to be inserted into the side rail 13 through an aperture 41 provided for that purpose. I also find it advantageous to malte the lower edges 37 of the inturned flanges 26 and 27 at such a height that they will rest within the apertured space somewhat below the top surface of the side rail 13, as is most clearly indicated in Fig. 5. I may depend upon the engagement of the lower edges 37 of the inturned flanges 26 and 27 with the walls of the side rail formed by the said aperture 41 to prevent the said inward sliding tendency of the riser, and I may also provide the said lower ends 37 of the inturned flanges 26 and 27 with downwardly projecting extensions which will more fully engage in the said aperture.

The said key 39 is of very simple construction and may be easily applied and operates to prevent the said inward sliding of the riser 14 by engagement between the lower portion of the enlarged surface 39 with the edge 42 of the aperture 41, and engagement of the tongue part 4() with the inner surface of the rail 13, as indicated at 43.

The strap 25 is cut away, as indicated a 44, in order to permit easy assembling of the riser and side rail. When these parts are to be assembled, the riser is held at an angle to the side rail 13 so that the rail may be read: ily inserted between the front edge 45 of the strap 25 and the lower edges 37 of the inturned flanges 26 and 27. Vhen the riser is at the proper position on the rail it may be then turned upwardly to form a substantial right angle with the rail, the key having been previously placed in the aperture 41. rIhe cross member 17 is then positioned on the riser 14 and the bed fabric stretched between the cross members at opposite ends of the vbed bottom. The bed bottom is then attached to the end frames 10 and 11 by engaging the studs 19 on the risers 14 with the hook-like member 18 on the corner posts of the end frames, as clearly shown in Fig. 2. The studs 19 are preferably provided with an enlarged head 46 to preventv displacement. The outer edge 47 of the upwardly extending arm 23 of the riser is adapted to engage the inner surface of the hook-like member, as indicated at 48, as best shown in Fig. 4, and the edge 39 of the hook member 18 is preferably inclined toward the post at the bottom whereby its engagement with the stud 19 will tend to clamp the edge 47 and face 48 tightly together, whereby the bed bottom is securely fastened to the end frames.

In order to permit passage of the riser 14 past the heads of the bolts 21, I prefer to cut out the lower corner of the riser, as indicated y at 50, and in order to improve the appearance of the finished structure I provide a cap 51 extending between the respective upwardly extending arms of the riser and secured thereto by suitable means such as a rivet 52 passing through a downturned lug 53 of the cap 51 and the arms of the riser.

I am aware that changes in the form and proportion of partsmay be made without departing from the "spirit of my invention, and I reserve the right to make all such riser and normally tending to move the samel inwardly along the rail, and means for preventing said inward movement comprising a key member seated in said aperture and having a tongue portion engaging the inside of one of said inwardly bent edges and another part projecting laterally from the side rail for engaging a part of the riser.

2. In a bedstead, the combination of a side rail and ariser seated on said side rail adjacent one end thereof, said riser comprising a member substantially U-shaped in vertical cross section, means for connecting the side portions of said U-shaped member to prevent spreading thereof comprising a pin having one end secured to one of said side portions, said pin extending crosswise of said U-shaped member and through the other side thereof and provided withan enlarged head portion engaging the outer face of said other side part, and means for connecting said side rail to a bedstead corner post comprising a bracket adapted to be secured to such post and provided with a hook part adapted to receive the enlarged head of said pin.
